Re: [MW:31291] Ground flush on weld seam required at intersection location

IMHO I believe the reason for grinding this type of weld joint flush is for a good clear X-ray with no multiple beads showing on the film and no weave, Clear. Many years ago

when I worked as a welder for CBI / PDM / etc we always ground this type of joint flush because we always flat topped all the X-ray joints. The weld joints were not ground 'flush',

they were 'flat topped', their is a difference. Flat topping a weld also gives a much clearer X-ray and it is faster than grinding joints flush. Also, I think tee joints could be called

the 'weak link' in a weld, so to speak. I know of no code reference but that doesn't mean their isn't one.

its a pleasure of mine if you show refference of this theory.

which code of construction you are using?

Dear experts,

Generally, standards say that "The weld seam shall be ground flush for a distance 50 mm on all sides of the intersection".

What is exact technical reason to do for ground flush on weld seam required at intersection location?
Thanks
